[Postoperative wound healing disorders]

Area of Science:

• Surgical Outcomes
• Infection Control
• Healthcare Quality Assurance

Background:

• Wound healing disorders and surgical site infections (SSIs) are critical metrics in surgical outcomes.
• Standardized nomenclature and surveillance systems are essential for accurate data collection.
• The relationship between wound healing disorders and SSI risk stratification requires further investigation.

Purpose of the Study:

• To investigate the incidence of wound healing disorders and their correlation with nosocomial operation categories and registered surgical site infections.
• To analyze trends in wound healing disorders and SSIs over a 20-year period.
• To explore the potential of wound healing disorders as indicators for surgical quality assurance.

Main Methods:

• Analysis of data from 33,336 operations over 20 years.
• Prospective registration of wound healing disorders and case histories.
• Categorization of operations based on nosocomial risk (A-D) and comparison with SSI rates.
• Monthly and long-term summarization of disorder and infection data.

Main Results:

• The 20-year summarized incidence rates were 2.2% for wound healing disorders and 2.7% for surgical site infections.
• Both wound healing disorders and SSIs showed diminishing rates in the latter half of the observation period.
• A significant correlation was observed: as SSI rates increased with operation category (A-D), so did wound healing disorder rates, though generally to a lesser extent.

Conclusions:

• Wound healing disorders and SSIs exhibit a complex, inversely related pattern when SSI rates are above or below 2%.
• Wound healing disorders may represent 'loci minoris resistentiae' that can either suppurate or not, depending on the operation's septic category.
• Wound healing disorder rates could potentially serve as novel indicators for evaluating and assuring surgical quality.
